Danfoss VLT 2800 Manual page 78

Remote controlled references are defined as:
- External references, such as analogue inputs
53 and 60, pulse references via terminal 33
and references from serial communication.
- Preset references.
The resulting reference can be shown on the LCP con-
trol unit's display by selecting Reference [%] in param-
eters 009-012 Display readout and can be shown as
one unit by selecting Reference [unit]. The sum of the
external references can be shown on the LCP control
unit's display as a % of the area from Minimum refer-
ence, Ref to Maximum reference, Ref
MIN
External reference, % [25] in parameters 009-012 Dis-
play readout if a readout is desired.
= factory setting, () = display text, [] = value for use in communication via serial communication port

It is possible to have both references and external ref-
erences simultaneously. In parameter 214 Reference
function a selection can be made to determine how
preset references should be added to the external ref-
erences.
There is also an independent local reference in pa-
rameter 003 Local reference, in which the resulting
reference is set using the [+/-] keys. When the local
reference has been selected, the output frequency
range is limited by parameter 201 Output frequency
